M'z'uiy banks of shale are otco'nsiderable thickness and area and many cofitaih pillars of othei ihaterial or unworkable qiielity.

The object of my present invention is to provide a readily controllable shalefof my planer by means of which the workable i501- tiohs of deposit may be simultaneously removed, as small pieces,ofrom a considerable vertical dimension bit the d'ejgiosit the apparates being of such character that it may be readily shifted to desired position hori- Zont'ally so that iiiide'sirable pillaf's in the de-' posit may be left untouched and Withbut interfering "with reinoi' al o'f desirable portions. 1 The accompanying drawings illustrate an elilbbtl'iihent Of iil'veiitioii.

The reduction gearing is such (conveniently of the Worni type) that, in the eperatisn of the device, movement of a track can only be accomplished by applicatiofi of force from motor 21 through the reduction gearing and hot by applieatioii of force to the tracks due to the resistahee'act- 'ing ii'pon the shale euttiiig elements, so that the machine is stable uiider its Work load;

Journ'alled upon the chassis on a central vertical this is a tiirii table structure 31 which carries the reductieh gear 20 and a Vertical shaft 32 eai'rying =1 pinion as (Fig. 2) which meshes With a large gear 34, fixed on the ehhssis and coaxial with the delivery shaft 30 or the redLiction gearing 20.

'22 aiid 36 iii a Well known manner, the armhgemeht beihg such that the turn tible m he swhhg in either direction through an desired angle.

Eiected at one side of the turn tible isja tower 40 conveniently twenty er mane feet in height. At the up er arid lower ehrl's of the tower 40 are shafts 41 aiid 42 eaii'ying sprocket Wheels 43 and 44, respectively, i v'hich caii ya chttei -cai'ryingchaiii C;

Gh'aiii C is composed (if a series of (Butter uiiits V and conneetin liiik sectioiis; Each rying a removable bit 51-, and thin-heavy guide links 52; 52; 5'2, 52 pivoted to the bit link and projecting, as tweg airs, fi'om opposite ends of the bit liiik; The intermediate chain sectioiis comprise sprocket engaging links 53 and connecting spacer liil'k pairs 54; the spacer links hai ihg the seine lehgth as the guide links 52 so that the bit liriks are sprcket-eiigagiiig elefnehts of the thain. The giiide' links are iiiade 'w'ider then the sweet liiilis al'idride in chahilel giiide's 55,

' cutter unit consists o a central lihk 50, car- I be clutched to it drive shaft 15 by a clutch 55, extending substantially the entire distance between sprocket wheels 43 and 44. By reason of the sliding engagement of the guidelinks 52 with the channel guides 55 each bit link is firmly supported to resist canting of the bit link as its bit engages the material of the bank 56 (Fig. 6).

Secured to shaft 42, upon opposite sides of sprocket wheel 44, are two sprocket wheels 0 60, 60 upon which are mounted sprocket chains 61, 61 also mounted upon sprocket wheels 62, 62 carried by a shaft 63 journalled at the upper end of an inclined chute 64 carried by the turn table and extending from 5 the lower end of the tower near shaft 42 to a hopper 65 also carried by the turn table.

Shaft 63 is driven, through a clutch 66 from a shaft 67 driven, through reduction gearing 68 from a shaft 69 driven, conveniently o by a belt 70 from a motor 71 mounted on the turn table. Clutch 66 may be manipulated by a lever 7 2 and motor 71 may be controlled by a controller 73.

Each chain 61 carries a series of scraper blades 76 the adjacent ends of which are spaced apart just enough to clear chain C, and these scraper blades, in the lower runs of chains 61, traverse chute 64.

The idle, or upwardly moving, run of chain C is carried through guides 80 (Fig. 3) to prevent sagging of this idle run against the active run, and the tower is boxed in, as indicated in Figs. 1 and 3, by the side walls 81, 81 and rear wall 82, thus confining the flying cut material and causing it to fall within the range of the scraper blades 76.

Arranged at each end of shaft 42 and supported on the turn table by a hinge 85 (Fig. 9) is a gathering wing 86 which serves, as the turn table is turned to scrape adjacent cuttings into the range of the scraper blades 76. The axis of each hinge 85 is substantially horizontal and at right angles to shaft 42 so that the trailing wing may swing up over debris from which the scraper blades 76 are being carried by turn-table movement but will drop down when, upon reversal of the turntable, the wing becomes the leading wing.

Projecting from the bottom of hopper 65 is a pivoted delivery chute 90 so arranged that a truck or car may be arranged beneath its outer end and this chute is traversed by the upper run of an endless conveyor 91 driven by a motor 92 controlled by a controller 94. The several controllers and shifting levers are conveniently grouped around a central point on the turn table where an operator may stand and readily control the various mechanisms to transport the device to any desired point; to move the cutter C toward the vertical face of a deposit to be worked; to swing the turn-table to cause the cutter C to traverse the face of the deposit, or if the tower is swung to a position at right angles to that hown in Fig. 3, to cause the cutter 0 tacked with the chassis tracks either at right angles to or parallel with the face of the deposit. lVith the chassis tracks at right angles to the deposit the turn table will be oscillated through an angle of 180 degrees or less and the chassis gradually advanced. With the chassis tracks parallel with the face of the deposit the turn table may be either held stationary or may be swung through a desired arc while the entire apparatus is advanced by driving the chassis tracks.

By reason of its great flexibility the structure may be manipulated so as to easily work around undesirable portions in a deposit and leave them stand even where they exist at irregular intervals, thus avoiding the necessity, which has heretofore existed of re1noving large masses of unusable material before desired material could be reached.

In order to assist in delivering the cut material to the scrapers 76 the construction shown in Figs. 12, 13 and 14 may be used. In this arrangement I mount on shaft 42, outside of sprockets 60, two hubs 95, 95, each of which carries a pair of oppositely inclined blades 96, 96, somewhat like propeller blades set angularly so as to scrape the cut material towards the adjacent scrapers. Each blade at its outer carrier is provided with a radial pocket 97 in which a cutter tooth 98 is mounted, said tooth being held in place by a set screw 99 and an adjustable abutment screw 100. The tooth 98 serves to scarify and loosen the floor, over which the work is proceeding, and the blades 96 scrape the loose material toward the scrapers 76.

I claim as my invention:

1. A shale-bank planer comprising a chassis of the double track-laying type, a turntable mounted on a vertical axis on said chassis, a tower carried by said turn-table, a driving shaft carried by said turn-table substantially at the ground level and in position to clear the track-laying elements of the chassis, an idler shaft carried at the upper end of the tower, an endless planer belt supported by 3 said driving shaft and idler, guideways in the tower engaging the active run of the planer belt, an upwardly and rearwardly inclined chute carried by the turn-table with its lower end closely adjacent the planer belt drive shaft, an endless scraper element traversing said chute and engaging said drive shaft, means carried by the turn-table for applying power to said drive shaft through said scraper element, means carried by the turn-table for rotating said turn-table upon the chassis, means carried by the turn-table for controlling the application of power to the track laying elements of the chassis, an endless conveyor carried bythe turn-table and arranged to receive the discharge from the upwardly inclined chute, means for supporting said last-mentioned conveyor to swing about a vertical axis on the turn-table, and means carried by the turn-table for controlling the application of power to said conveyer.

2. A shale-bank planer comprising a tower structure, a supporting chassis for said tower structure, a drive shaft journaled at the lower end of said tower structure and carrying three sprocket wheels, an idler sprocket journaled at the upper end of the tower, an endless planer belt comprising a plurality of aligned bit carrying links and a plurality of pairs of connecting links, said planer belt engaging the middle sprocket of the lower shaft and being supported by the idler sprocket, a pair of guides carried by the tower and receiving and guiding each two pairs of links immediately adjacent each bit-carrying link, an upwardly and rearwardly inclined conveyor chute with its lower end immediately adjacent the first-mentioned sprocket shaft, two endless scraper chambers mounted upon the two outer sprockets of the first-mentioned shaft and each carrying scraper elements closely flanking the planer belt and traversing the chute, and means for applying power to the planer belt through said scraper belts.

In witness whereof, I have hereunto set my hand at Indianapolis, Indiana, this 24th day of November, A. D. one thousand nine hundred and twenty-eight.
